Main project: CO2 post-combustion capture by means of membrane absorption-crystallization using amino-acid salts
Funding: ERC
Supervisor(s): Patricia Luis Alconero

Climate change remains a huge challenge today. The most mature and popular CO2 capture method in post-combustion processes is the absorption of CO2 into a solvent, often MEA. Nevertheless it has been shown that this method could be improved both in terms of solvent and in terms of device. The project aims at studying the CO2 post-combustion capture by means of membrane absorption with amino-acid salts and convert the absorbed species into valuable carbonate crystals after a concentration step by means of a reverse osmosis (RO) membrane. The crystallization will be performed thanks to a membrane distillation-crystallization step. A comparison between the osmotic membrane distillation system and the vacuum membrane distillation system will be performed. This whole process should minimize the energy consumption thanks to the use of membrane technologies instead of absorbtion columns while producing pure crystals that could be sold in the industry.
